An eponym is a common noun, verb, or adjective that takes its name from a real historical person, fictional character, or mythological figure.
Eponyms represent one of the most colourful chapters in linguistic history. Derived from Greek eponymos (epi "upon" + onyma "name"), they immortalize inventors, generals, aristocrats, and victims of historical circumstances. When Earl of Sandwich requested slices of roast beef between bread so he could gamble at cards without greasy fingers, the "sandwich" entered the global lexicon. When Irish tenant farmers ostracized landlord agent Captain Charles Boycott in 1880, "boycott" became an international verb.
